Interpretation of Results There are different types where diodes can be applied and one if it is using it as a clamper in a circuit. A clamper circuit is consisting of a capacitor and a diode for it to clamp. A diode can either face upward or downward, left or right in a circuit. For a diode that is facing downward and is parallel to the output terminal, the output waveform will then be shifting downwards. When the voltage applied to the circuit is increased, the output waveform will be able to return to its original wave input. A circuit is called a clamper or a dc restorer when the input waveform is maintained throughout the cycles while having the only difference in it is the shifting or location of the output waveform. There is a difference between a Clamper Diode and a Clipper Diode. A Clipper clips or removes a certain portion of the input wave (it can be the positive half-cycle, negative halfcycle or even both) to the output wave while retaining its original position in the graph. While for a Clamper Diode, the output wave shifts depending on the orientation of the diode in the circuit while the shape form of the input wave is retained. A biased clipper, has the value of the bias generally affects the output voltage of a circuit. When the diode is in forward bias, the output shifts upwards while when in reverse bias the output wave shifts downwards. This is all due to the orientation of the diode in the circuit. The Oscilloscope and LTSpice IV are in agreement with its value, making the group conclude that the clamper diode used in the experiment is in good condition.

Conclusion In conclusion, the diodes have many useful applications in a circuit such as Clippers and Clampers. As stated in the interpretation of data, a clamper is a type of diode circuit in which an additional component, the capacitor is used to store the energy. The Clamper has two types, the Positive Clamper and Negative Clamper. A positive clamper shifts the output wave upward while the negative clamper shifts the output wave downward both with respect to the reference value. The orientation of the diode in the circuit determines the shifting of the output wave. If the diode is pointing upwards (the cathode is above the anode), then the expected output will shift upward. If the diode is pointing downward (the anode is above the cathode), then the expected output will shift downward. Summarizing all the gathered data and observations the group can say that we have met the objectives as per stated in the manual. Thus, making us learn more about capacitors and diode. The role of the capacitor is to store the energy to be used in the clamper shifting process. A diode clamper circuit is responsible in shifting the voltages in a circuit.
